“…Comparison with the results from the interlaboratory study Table 6 contrasts the results obtained in our laboratory with those of the second round-robin exercise on lead speciation. 26 The results from the analysis of the different rainwater dilutions showed very good agreement with the mean values of the interlaboratory study. A difference was observed between the results of the road dust analysis.…”

A rapid and sensitive method for the determination of trimethyl-lead in water and road dust is described. It is based on in situ ethylation of ionic methyl-lead by sodium tetraethylborate and the extraction of the compound formed into hexane. The extract is gas-chromatographed and the lead species determined by microwave-induced plasma atomic emission spectrometry (MIP-AES). The reaction conditions are optimized and the method is applied to the analysis of artificial rainwater and road dust in the framework of an international round-robin exercise.

“…Therefore, for complex matrixes such as sediments containing a large fraction of organic carbon or for sewage sludge samples, standard addition has been considered so far to be the only possibility to provide sufficient quality assurance. 37 In this work, we describe two new analytical methods for the routine quantification of butyltin and phenyltin compounds in natural waters and sediments. For water samples the method includes aqueous ethylation followed by liquid-liquid extraction (LLE) or solid-phase extraction (SPE) and quantification by largevolume-injection GC/MS.…”

Two new methods for the simultaneous identification and quantification of organotin compounds (OTs) including monobutyltin, dibutyltin, tributyltin, monophenyltin, diphenyltin, triphenyltin, and tricyclohexyltin (TCyT) in natural waters and sediments, respectively, are presented. For water samples, aqueous ethylation followed by liquid−liquid extraction (LLE) or solid-phase extraction and large-volume-injection GC/MS (50−200 μL) were used. For sediment samples, accelerated solvent extraction at 100 °C with a methanolic mixture of sodium acetate and acetic acid was developed. By using for the first time perdeuterated OTs as internal standards, excellent precision (relative standard deviations <5%) and low method detection limits ranging from 0.3 to 1.5 ng/L for 50 mL of aqueous samples and from 0.4 to 2 ng/g for 2.5 g of dried sediments were achieved. Using LLE, recoveries determined in spiked harbor water (+5 ng/L) and sediment pore water (+25 ng/L) were in the range of 93−103 (RSD 0.5−4.6%) and 97−108% (RSD 0.8−4.2%), respectively. For spiked sediment samples (+10 ng/g) recoveries of 98−105% (RSD 1−7%) were achieved for all OTs, except for TCyT (51%, RSD 4%). The developed analytical procedures were validated with reference material and applied to various environmental samples, such as fresh- and seawater, field runoff, wastewater, sediments, and sewage sludge.

Organotin contamination of the marine environment can be considered one of the main environmental problems in the last 20 years. Starting from the ‘Arcachon case’, monitoring campaigns have been carried out worldwide in order to evaluate the concentration levels of these compounds in the marine environment. In 1987 the EC Standards, Measurements and Testing Programme (formerly BCR) started a ‘tin speciation’ project to assess and improve the quality of measurements in this field and to make available reference materials. Ten years of study within the framework of this project have produced results in the fields of method development and production of reference materials, particularly for butyltins. The quality of the phenyltin analytical results was lower than for butyltins and further efforts are still needed. To overcome this shortfall, the last certification campaign was aimed towards the certification of phenyltins, as well as butyltins, in a candidate mussel certified Reference Material. The results of the homogeneity and stability tests for phenyltins and of the certification campaign are presented here. The preparation of the material and the analytical methods used in the certification campaigns are also described. The certification of phenyltins was hindered by their lack of long‐term stability; nevertheless, the exercise provided information about the state‐of‐the‐art of phenyltin measurements in biological samples. © 1998 John Wiley & Sons, Ltd.
